Quatz reload?

[(PSN)dieyungsveyurslf]

Just crafted quatz and noticed that it will reload on its own before the magazine is empty. I made sure I wasn't pressing reload or pressing in thumb sticks and I noticed that after 12 rounds it reloaded in full auto then another time after 8 rounds (2 shots in semi auto). This will happen consistently too and seems random so unfortunately i can't say it happens at after performing something specific. I haven't seen anything online or in forums so it might need to be looked into.. I sent a ticket in just in case because I'm not sure if this is just a user forum or if developer techs use this also...
